introduction: during radiotherapy, high accuracy in the dose delivery is required because there is a strong  relationship between the absorbed dose, local tumor control and particularly the normal tissue damage. in  many institutions, in vivo dosimetry using diodes is performed to check the actual dose delivered. in general,  the uncertainty in the dose delivered should fall within  ± 5% of the...

Introduction. Brain tumors are a complex problem of modern neurosurgery. Meningiomas, mostly benign tumors, can become when they difficult to locate. The complexity is also caused by affecting the sinuses brain. In this case, surgeon faces number issues related diagnosis, preoperative planning and choice treatment tactics for these patients. in favor revascularization venous bed not always unam...

In recent years, brain tumors become the leading cause of death in the world. Detection and rapid classification of this tumor are very important and may indicate the likely diagnosis and treatment strategy. In this paper, we propose deep learning techniques based on the combinations of pre-trained VGG-16 CNNs to classify three types of brain tumors (i.e., meningioma, glioma, and pituitary tumo...

Brain tumors, which is one of the destructive forms of human being’s cancers, are the second most common children’s cancers. Brain tumors may have an inherited (small percent), acquired reasons due to environmental factors. Nowadays advances in cosmetic industry have increased our ability in the field of youth and beauty. Hair dye products are such innovations. Recent studies showed...

we report a patient diagnosed with whipple's disease (wd) who presented only with neurological symptoms. neuroimaging (mri) showed lesions with marked mass effect similar to infiltrative tumors, which were hypersignal on long tr and hyposignal on short tr images, located in several areas of the brain. in serial controls, lesions resolved with gliosis and atrophic changes as well as migration of...

A tumor-infected brain is a dreadful illness. It an area in the caused by cell development irregularity. An infected might be challenging to identify and categorize using MR imaging approach. Images of human anatomy are resulted various methods. Strange compositions difficult detect standard image processing MRI differentiates explains neurological design. This research proposed analytical meth...
